A report on the alimentary canal helminthic infestation of stray and pet dogs in Tabriz

From September to December 2007, fecal specimens of 100 stray and pet dogs in Tabriz were examined by saturated salt flotation and Telmann sedimentation methods to determine the prevalence of gastrointestinal helminth infestation. Helminth infestation was encountered in 31 (31%) of the fecal samples examined. The eggs of two different cestodes and three different nematodes were identified in the contaminated fecal samples. The helminth eggs found were identified as Taenia hydatigena (4%), Dipylidium caninum (6%), Toxocara canis (10%), Ancylostoma caninum (6%) and Trichuris vulpis (5%). No trematoda eggs and nematode larvae were found in this study.
